Risk-Based Predictive Maintenance for Safety-Critical Systems by Using Probabilistic Inference

Table 3

Consequence resulted from different subsystem failure scenario.

𝐹^𝑡1	𝐹^𝑡2	⋯	𝐹^𝑡𝑁	Consequence
Ok	Ok	⋯	Ok	No
Fail	Ok	⋯	Ok	Insignificant
Fail	Fail	⋯	Ok	Marginal (minor injury)
Fail	Fail	⋯	Ok	Critical (single severe injury)
Fail	Fail	⋯	Fail	Catastrophic (fatalities)
